The Miniflex One-Pak is a portable and effective solution for the removal and filtration of welding fumes in confined and other hard to reach spaces. Unlike other bulkier welding fume extractors, the Miniflex leads the industry in portability and ease of use. The One-Pak includes the 8-foot extraction hose along with the EN 20 extraction nozzle with magnetic base.

The miniflex uses a 5 stage filtration process.
• Stage 1 - Air passes through a removable/washable pre-filter where heavier particles and foreign material are captured in the collection tray.
• Stage 2 - Air passes through a second pre-separator to further reduce medium to heavy particulate matter.
• Stage 3 - Air passes through the LongLife-H filter where welding fume particles are captured and deposited.
• Stage 4 - Activated carbon filter (optional) will help prevent or neutralize the release of odors back into the environment.
• Stage 5 - Final filtration as air passes through the HEPA H12 class filter.
